There is config.ini file in game folder. A lot of options can be changed to make game run smoother and better or just to change hotkeys. Today some description were added to make it easy to understnd. Look for render option!!! Canvas render makes game run better for computers with weak videocards but good CPUs. I've tryed it on my laptop. Changing it made it playable even there. Try different options hope that would be helpful.
